JULES BREU'CI-IAUD, OF YONKERS, NEW YORK, ASSIGNOR TO THE UNDERPINNING- COMPANY, or NEW YORK, N. Y.,

A CORPORATION OF NEI/V YORK.

SUPPORT AFOR BUILDING-WALLS, &c.

Specification of Letters Patent. Patented June 27, 1911.

Original application led April 2, 1909, Serial'No. 487,543. Divided. and. this application filed November 4,

Serial No. 526,194.

To all whom it may concern:

Be it known that I, JULES BREUCHAUD, a Vcitizen ofthe United Sta-tes, residing at Yonkers, in the county of Westchester and State kof New York, have invented certain new and useful Improvements in Supports for Building-lValls, &c., of which the following is a full, clear, and exact specification.

My invention relates to an improvement in supports for building walls or other f structures, or providing new and improved foundations therefor, and is a division of my prior application Serial No. 487,543, filed April 2, 1909, and relates particularly to the new foundation described therein. The method which Ipreferably employ to produce such new foundation is fully set out therein and will be briefly described hereinafter.

The invention forming the subject-matter of the present application has for its object to provide a foundation which shall possess increased lateral strength and stability, and one which will not readily yield under increased lateral pressure. Furthermore, although said found ation possesses the advantage of a sectional construction, by reason of its characteristic features it is substantially water-repellent without the necessity for sealing the joints between sect-ions and may safely be passed through a water-bearing strata without danger of any objectionable iniiow of water.

My invention consists in the formation of a support for a building wall or other structure, of a plurality of sectional columns arranged concentrically and fitting somewhat snugly, and arranged so as to break joints. These several columns have their upper ends substantially even so as to receive uniformly the weight of the structure to be supported, and their lower ends are situated at progressively-increasing depths, the outer column being the shortest and the innermost column the longest.

Although I have illustrated the support as applied to a building wall, it is equally applicable to other uses, such as piers, statues, etc.

In the accompanying drawings illustrating an embodiment of my invention Figure 1 is a transverse sectional elevation of the lower part of a building wall, and my irn- 'proved support in place, but not lled nor connected. Fig. 2 is an elevation of the face of the lower part of a building wall, illustrating the foundation partly constructed. 3 is a cross-section on the line 3 3 of 1F ig. 1. Fig. 4 is an elevation of the lower i part of a building wall with two supporting columns and illustrating a connection bevtween said columns and the wall; and Fig. f 5 is a vertical section on line 5-5 of F ig. 4.

The support is composed of sectional cy lindrical shells located in a plurality of con- Icentric columns. The outer column is the shortest and will usually comprise but a sin- `gle cylindrical section 1. Located within "this is the second column composed of two cylindrical sections 2, 3. The upper ends of cylinders 1 and 2 are even, but their lower ends terminate at different levels and break joints, whereby the lateral strength of the vstructure is increased and its ability to eX- `clude water also increased. The third column is similarly disposed, fitting snugly within the second, and is composed of cylindrical sections 4, 5, 6, and this carries down the support one section deeper. I have illustrated the foundation as comprising four columns, although a smaller or greater number might be required. The fourth or inner column has four sections designated 7 8, 9, 10. These columns may be formed of any suitable material, such as cast iron, and it is preferred that no joint in any pipe shall be opposite a joint in any other pipe. The inner column is filled with concrete or other suitable filling (Fig. 5), and the entire support is capped with a distributing block 11, by which the weight is evenly distributed upon the several columns. The columns are located under the wall or other `structure 12, at convenient distances apart, and beams 13 are then placed upon the caps 11. These beams are of proper length, so that they will extend approximately half-way across each cap on adjacent supports. Beams 14 are located above the beams 13 and under the wall, and a number of wedges 15 are tightly located between the two sets of beams,` transmitting the weight of the wall to the sup ports.

Any suitable means may be employed to locate the supporting elements in position. Where they are sunk as a new foundation erected, they may be sunk in a manner similar to that in which caissons are sunk with the aid of compressed air if water is present, or by the aid of a water jet. A pile driver may be used. When sunk under an existing structure, as a building wall, the method of my Patent No. 563,130 may be employed; or they may be sunk by means of a steam hammer, or by other hammer, as electric, pneumatic, etc., capable of delivering a rapid succession of short, sharp blows in the following manner: A recess 20 is formed in the wall near its base and eXl tending to the vsoil within which the first section 1 is placed. Blocking is employed and the hammer located so as to drive this section into the soil. A water jet may be employed which will facilitate the driving and float oftl the soil, or the cylinder may be excavated after driving. Section Vl having been cleaned out, section 3 is then located within it, fitting snugly thereto and easily driven to theA depth of section l. A third section 2, of the same diameter as section 3, is then located above section 3, and blocking and driving again resorted to until the upper ends of sections 1 and 3 are flush. The sections composing the succeeding columns will be similarly driven and cleared of soil and the completed structure filled with concrete, capped. Beams will then be located so as to rest on adjacent columns, and other beams located above them and beneath the wall, and wedges driven until the weight of the wall is taken on the columns.

I claim:

l. A foundation comprising a plurality of concentric, hollow, snuglyfitting columns having their upper ends substantially even and their footings at progressively lower points from the outermost to the innermost cylinders.

2. A foundation comprising a plurality of concentric, hollow, snugly-fitting sectional columns having their upper ends substantially even and their footings at progressively-lower points from the outermost to the innermost cylinders. f

3. A foundation for a building wall comprising a plurality of hollow columns composed of snugly fitting concentric cylinders, each of which is of the same diameter throughout, having their lower ends eXtending to progressively-increasing depths, the interior column being the deepest.

4. A foundation for a building wall comprising a plurality of hollow snugly fitting concentric columns, each of the same diameter throughout and composed of sections, the upper ends of the columns being substantially even, and the lower end of each column being at a greater depth than its surrounding column.

5. A foundation for a building wall comprising a plurality of concentric columns, each composed of sections, the lower end of each column being at a greater depth than its surrounding column and a connection therefrom to said wall providing a substantially uniform and continuous supportv for the entire base of the wall, comprising beams connecting the upper ends of adjacent columns, beams located in the wall and wedges driven between said two sets of beams.

6. A foundation composed of a plurality of hollow, snugly-fitting, concentric columns, each column comprising a plurality of sections of the same diameter throughout, the lower ends of the columns increasingin depth as they approach the center of the pile.

7 A foundation composed of a plurality of concentric, snugly-fitting pipes, each pipe comprising a plurality of sections of uniform diameter, the concentric sections being so disposed as to break joints, and the. lower ends of the respective pipes being located at progressively-lower points as they approach lower depths from the outer pipe to the Vinner pipe.

In testimony whereof,I have hereunto set my hand in the presence of two subscribing witnesses.
